Polyimide flexible heater
Polyimide flexible heater (short for PI flexible heater), its conductor is made of copper or 304 stainless steel, copper foil conductor is similar to our commonly used FPC, conductor copper foil 304 stainless steel is sandwiched between two layers of polyimide film using FEP adhesive or acrylic adhesive, this heater is very thin, it can reach 0.1mm thickness, And the temperature can reach -40℃-200℃ (long-term use below 150℃)
Due to their thin and light capability, polyimide flexible heaters are suitable for applications where additional weight problems may occur in working equipment, or equipment with minimal available space; It has excellent heat transfer performance and is usually used in harsh environment applications where durability is required. They exist in the aerospace, food service, military, and medical industries. The Polyimide PI flexible heater can also be used indoors and outdoors.
Silicone Rubber flexible heater
Silicone Rubber flexible heater is two layers of Silicone Rubber insulation layer sandwiched with a layer of heating conductor, it will be heating after electricity, the required temperature can be adjusted according to the resistance value of the heating conductor, it’s thicker than PI but more resistant to temperature and more buffering. Its thickness can reach 1mm-3mm, temperature can reach -40℃ - 280℃ (long-term use below 250℃).Transparent flexible heaters also known as PET heaters, they are customized for applications that require a lower heating transfer, and their transparent properties are suitable for visual equipment to remove moisture or ice on the product surface. such as de-icing mirrors, heating batteries, restaurants that keep food ingredients at the desired temperature, heating fish tanks, and heating cups inside coffee machines.
